as I see, you have a number of partially unrelated issues and
you've definitely chosen a host distro which probably will
give you a lot more trouble (due to outdated and broken
packages) than necessary ... in any case:

what kernel/patch/util-vserver version do you use?

you're aware that xdm/gdm/kdm require an X11 to display
on, so they 'normally' start one (or a number of them)

at least gdm sources a lot more config files than just
the 'one and only' main config file, so I'd check for
(maybe hidden) includes and other places where kdm
configs might reside (strace -fF should help with that)

if there is no initctl, chances are good that your
guest doesn't have/run a real init process, in which
case that is not unexpected ...

a fifo where nobody listens is practically useless
i.e. similar to /dev/null and for initless guests, you
can select the runlevel in the guest config

no idea, that seems to be suse specific and I stopped
using suse a long time ago ... but maybe somebody knows
(again strace -fF might be of help)
